摘　　要：计算了Ｅｒ３＋掺杂的氟氧化物玻璃材料ＭＦＴ的Ｊ－Ｏ参数，进而获得了一些能级间跃 迁的跃迁几率、分支比、及寿命等数据．测量了室温下Ｅｒ３＋的较强的两个绿色发射２Ｈ１１／２、 ４Ｓ３／２→４Ｉ１５／２及红色发射４Ｆ９／２→４Ｉ１５／２的激发光谱，观测２Ｈ１１／２、４Ｓ３／２→４Ｉ１５／２跃迁 荧光强度随着温度的变化，测量了室温下这两个跃迁衰减曲线，计算了这两个能级的无辐射跃 迁几率及量子效率．The optical transitions intensity parameters of Er3+ in MFT glass were calculated by using the J-O theory. The transition probabilities, branching ratios and lifetimes of Er3+ ion were obtained. The excitation spectra were measured monitored at intense green of 2H11/2, 4S3/2→ 4I15/2 transitions and red fluorescence of 4F9/2 → 4I15/2 transition of Er3+ ion. The fluorescence intensity variation with temperature for 2H11/2, 4S3/2→ 4I15/2 transitions was observed. The fluorescence decay of 2H11/2, 4S3/2→4I15/2 transitions was measured and the quantum efficiency and non-radiative transition rates were calculated.
